Fig. 11 AttachiFig. 14ng Pedals Your e-bike may be fitted with an adjustable stem, a standard quill stem, or a threadless stem (Refer to Fig. 12). Regardless of stem type, always check that all the bolts are tight before riding. Respect the stem type and follow the instruction below:

1. For Quill Stem: Insert the handlebar stem into the fork steer tube to the minimum height line that is marked on the side of the handlebar stem. It may be necessary to loosen the stem Expander Bolt so that the stem can slide into the fork tube, until you get your desired height of the handlebar stem. For Threadless Stem: Slide the stem over the fork steer tube.

2. Align the handlebar stem with the front wheel (See Fig. 13). Securely tighten the stem bolt(s). Note: Some models require a 6mm hex key. (Tightening torque: 18N.m or 14foot lbs.torque).

3. Positioning the Handlebar: • Loosen the stem handlebar clamp bolt (Quill) or hex bolts (Threadless). • Position the handlebar at the desired angle. Make sure the handlebar is in the center of the stem handlebar clamp. • Tighten the handlebar clamp bolt (tightening torque: 18N.m or 14footlbs.lbs).

4. Be sure that your handlebar and stem assembly is properly tightened before riding. The handlebar and stem should not rotate in the stem up or down or in the fork from left or right. (Fig. 13)

Checking Brake Pad Wear, Pad Replacement assembly, adjustment, and maintenance. Pads that are 1mm thick (or less) need immediate replacement (Fig. 18). A. Brake Lever and and Brake Pad Travel Adjustment You can adjust the amount of braking leverage by adjusting the brake lever travel and by the closeness of the brake pads to the brake disc.

Brake Lever/Cable Adjustment: To adjust the travel of the brake lever, loosen the Locking Collar A1 (away from lever body), turn/unscrew the Adjusting Barrel A2 (what the cable enters) left/counter- clockwise which tightens cable tension and increase lever travel & leverage, this will bring the caliper brake pads closer to A2 A1 the disc (Fig. 15). If the pads are rubbing against the disc, reverse the process. If you have tuned the Adjusting Barrel Fig. 13 Brake LeverFig. Adjustment15 Fig. 16 Fig. 17 to its maximum and the lever travel is Fig. 18 Fig. 19 still excessive you will have to adjust the space between the pads and the disc. Tighten the Locking Collar up to the lever body. To install new pads, remove the brake caliper from the fork or frame by unscrewing Additional adjustments at the caliper (Fig. 16). hex bolts D (Fig. 19). Unscrew (left/counterclockwise), the smaller hex bolt inside allen bolt B (Fig.14). Lift up and pull the inner pad downward, using the protruding tab. Slide Caliper Adjustment: Insert a hex key into the smaller hole inside hex key hole B a thin slot screwdriver under the outer pad and lift it up. Hold the screwdriver in this (Fig.16). Rotating the allen key clockwise/right pushes the outer brake pad forward by position and remove the pad with a pair of long- nosed pliers. approx.0.8mm. After each turn, check the braking function, so the pads are close, but do not rub the disc. Remove the springs from the worn-out pads and fit them onto the new pads. Replace the new pads, keeping them slightly inclined into the seat of the Caliper.

Check that the spring hooks correctly onto the small piston. (When pulling downwards the pads should not come out). Refit the Caliper to the fork (or frame for rear brake). Turn adjuster screw C (Fig.17) until the pads are centered on the disc and the wheel spins freely. Again, there may be some noise from the brake until it “bed” in.

Before riding, lift the front of the bicycle so that the front wheel is off the ground, lightly bounce it to the ground and give the top of the tire a few downward strikes. The wheel should not wobble or come off and there should be no rattling. Do the same for the rear wheel.
